Analog signal processing

Samar Ansari's Research InterestsAnalog signal processing deals with operations on or analysis of signals that have not been digitized, as in classical radio, telephone, radar, and television systems. This involves linear electronic circuits such as passive filters, active filters, additive mixers, integrators and delay lines. It also involves non-linear circuits such as compandors, multipliers (frequency mixers and voltage-controlled amplifiers), voltage-controlled filters, voltage-controlled oscillators and phase-locked loops.

neural networks

Samar Ansari's Research InterestsAn artificial neural network (ANN) is a computational model inspired by the structure and/or functional aspects of biological neural networks. An ANN consists of an interconnected group of artificial neurons, and  processes information using a connectionist approach to computation. Massive parallelism and fast convergence are  the biggest attractions. Modern ANNs are non-linear statistical data modeling tools and may also be used for computationally intensive problems.
